REMOVABLE BOTTLE CAP Filed NOV. 15, 1943 Patented Apr. 10, 1945 UNITEDSTATES PATENT OFFlCE REMOVABLE BOTTLE CAP Bertram C. Tate, Brooklyn, N.Y.

Application November 15, 1943, Serial No. 510,343 (01. 215-46) 1 Claim.

The invention relates to bottle caps, and more especially quickremovable bottle caps.

The primary object of the invention is the provision of a cap of thischaracter, wherein the same is so constructed that it can be removedwithout the use of a special tool or the'usual bottle cap opener, thesaid cap being detached by the said cap can be easily and quicklyremoved from the bottle.

A further object of the invention is the provision. of a cap of thischaracter, wherein the clinching of the same to the bottle is had byindentations, these reinforcing the flange of the cap in addiiton tosecuring the cap in place on the bottle, the flange being cut into toeffect releasing tabs or lips for the quick removal of the cap from thebottle, without the use of an instrument for so doing.

A still further object of the invention is the provision of a cap ofthis character, which is simple in construction, thoroughly reliable andefficient in its purpose, strong, durable, and inexpensive tomanufacture and install.

With these and other objects in view the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described, illustrated in the accompanyingdrawing, which shows the preferred form, and pointed out in the claimhereunto appended.

In the accompanying drawing:

Figure 1 is. a top plan view partly in section of the cap constructed inaccordance with the invention.

Figure 2 is a side view thereof.

Figure 3 is a sectional view on the line 3-4 of Figure 1.

Figure 4 is a sectional View on the line 44 of Figure 1.

Fgure 5 is a sectional view on the line 5-5 of Figure 1.

Figure 6 is a bottom plan view of the ,cap.

.Figure 7 is a fragmentary detail view.

Figure 8 is a view similar to Figure 7 showing one of the indentationsopened.

Similar reference characters indicate corresponding parts throughout theseveral views .in the drawing.

Referring to the drawing in detail A designates generally a portion ofthe neck of a bottle having at the open mouth end In thereof an externalan.

nular bead I I as usual for the fastening of a can generally denoted atB thereto, and constructed in accordance with the invention ashereinafter set forth,

The cap B comprises a circular metal crown I2, although the material maybe other than metal having inherent springy character, formed with acorrugated flared skirt I3 providing vertical outstruck ribs I4 andinstruck indentations I5} alternating therewith, the latter being forthe crimping or clinching of the skirt I3 to the bead I I on the mouthend In of the neck A of a bottle. The ribs I4 are vertically slitted atI6 in the lower portions thereof, and next to an outturned flange IIconcentric to the skirt and unitary therewith, the flange I! beingturned upwardly and inwardly on itself throughout the extent thereof toprovide an outwardly inclined overhanging lip I 8 with-relation to thesaid flange IT.

This lip I8 has notches I9 therein registering with the ribs I4 for theinterfitting of the latter therein. The flange I1 and lip I8 areradially slotted at '20, these being diametrically opposed to each otherat four points circumferentially of the crown I2 and the inner ends ofthese slots 20 terminate within the indentations I5 next thereto, so asto provide independent finger releasing'tabs 2I about the said crown I2,to permit the easy and quick release of the cap from the bottle by handpressure upon a selected tab 2 I.

When an upward pressure is exerted upon a selected tab 2| the cap Bbecomes loose upon the bottle and such cap by further upward pull byhand thereon is removed from the said bottle.

The lip I8 fulcrums on the ribs I4 when an upwardly directed force isapplied to a tab 2|, and thereby releasing the crimping engagement ofthe cap with the-bottle mouth end I 0. The slits I6 in the ribs I4 openduring the upward pressure upon the flange I! for the freeing of the capfrom the bottle, these slits I6 being normally closed.

What is claimed is:

A bottle cap comprising a crown portion having a flared skirt providingalternating ribs and indentations when crimped upon a bottle mouth, theribs having their lower portions vertically slitted, a radially slittedflange extending outwardly from the lower edge of the skirt, and aradially slitted lip overlying the flange and extending inwardly andupwardly from its periphery, the inner edge of the lip having recessesreceiving the ribs, and the inner edge of the lip being adapted tocontact with the ribs when upper pressure is applied to the flangewhere-by to provide a fulcrum on which the flange moves to release theskirt from the bottle.
